I’ve tested this with a Samsung S8 phone and RiftCat VRidge VR viewer worked perfectly with SlicerVirtualReality extension.
I’ve used Windows 10 and USB connection. Installation takes 5-10 minutes, as you need to install a companion app on the desktop computer, and on your phone the VRidge app and a VR sideload app. All the steps are very clearly described though. You also need to install Steam and SteamVR, if you haven’t installed those before.
